An example of good design is the exploredc.org site, mostly because it is highly structured and yet very easy to navigate. This is especially apparent when you get into the content of the site. The color scheme gives it a nice uniformity and the colors are unobtrusive. More importantly, they are used well to delineate different sections of each page (menu bar on the side for the topic at hand, menu bar across the top for all the topics, and white for body text). Links and layers (photographs, audio, lesson plans) are all neatly laid out and are accessible either as a group from the home page or in relation to a topic (linked from the topic page). The use of art is minimal (only as menu headers), which makes the page seem very professional.
